When wearing a yukata or kimono, you use towels and other items for padding... By wrapping it over undergarments, I think it can make your waist more cylindrical, making it easier to tie the obi. This is made by folding two commercially available towels (32-35 cm wide, 75-80 cm long) in half and attaching a string (80-90 cm long). You wrap it around your waist, cross it in the back, and tie it in the front. I received a message from a customer who purchased one saying they preferred it without Velcro. I think strings are easier for anyone to use. When wearing a yukata, etc... It's made with towels and tenugui (hand towels) and double gauze, so it absorbs sweat. I try to sew carefully, but it is handmade by an amateur, so please understand any imperfections before purchasing. I may use recycled wrapping paper for shipping, so please be aware of this. ★I am also listing this on other sites, so please understand that I will give priority to the person who purchases it first.
